Hackers have stolen the personal information of about 1.5 million people in Singapore, including Prime Minister Lee Hsien Loong, who was specifically targeted in the "unprecedented" cyberattack.
The Health Ministry said on Friday that the "deliberate, targeted and well-planned," attack on Singapore's government health database aimed at patients who visited clinics between May 2015 and July 4 this year.
"It was not the work of casual hackers or criminal gangs," the ministry said in a statement, adding that the attackers targeted details about Lee and the medicines he received.
"The attackers specifically and repeatedly targeted Prime Minister Lee Hsien Loong’s personal particulars and information on his outpatient dispensed medicines," it said.
